Abstract

Addressing the problem of increasingly complex urban household waste requires a multi-aspect approach. This study, therefore, aimed to develop a strategy to manage household wastes in the city of Banda Aceh based on five aspects including policy, institutional, funding, community participation, and operational technique aspects. It was conducted using in-depth interviews with garbage experts and a review of national and municipal policy documents. The qualitative data obtained was processed using Nvivo software. The investigation revealed that legal foundation of municipal waste management derived from the national and city level whereas there is no legal basis at provincial and village levels. In the perspective of institutional aspect, lack of management personnel, budget allocation, and coordination among the key stakeholder have contributed to weak institutions. As regards technical operation aspect, it can be further improved by proper sorting of waste, use of temporary disposal sites, swift waste transportation, time management of waste transportation and non-single use material campaign. Therefore, these aspects need to be developed sustainably to achieve the target of 30% waste reduction by 2025.

Abstract

Green belts play an important role in reducing greenhouse gas emissions in urban areas. This study aims to determine the total carbon stock and carbon absorption capacity of vegetation along the green belt of Dr. Ir. H. Soekarno IIC Road (MERR) in Surabaya, and to analyze the extent to which vegetation can reduce carbon dioxide (CO₂) and carbon monoxide (CO) emissions produced by motor vehicles. The method used in this study involves direct measurement of vegetation parameters such as tree diameter and height, which are then processed using biomass estimation and carbon stock conversion factors. In addition, CO₂ emissions are estimated based on traffic volume data and emission factors for each type of vehicle. The results show that the vegetation in the MERR IIC green belt is able to store a certain amount of carbon and has potential in absorbing CO₂ emissions, although it is still not proportional to the total emissions produced by motor vehicles per day. Therefore, improving the quality and quantity of vegetation in urban green belts is crucial to support air pollution control efforts in urban areas.

Abstract

Water pollution, particularly from textile industry waste, has become an increasingly significant environmental issue. Textile waste, especially synthetic dyes, contributes substantially to water pollution because of its complex structure and low biodegradability. Dyes such as Remazol Brilliant Red and Remazol Turquoise Blue, which are commonly used in the textile industry, are stable, toxic, and difficult to degrade biologically. One promising approach to address this issue is photocatalysis using photocatalysts such as CuO and CeO₂, which possess high degradation capabilities for organic contaminants. This study explored the effectiveness of CuO-CeO₂-based photocatalysts in degrading Remazol Turquoise Blue and Remazol Brilliant Red dyes. Photocatalysts were synthesized with varying CuO-CeO₂ concentrations, and degradation tests were conducted using UV light to observe dye degradation. The results show that the CuO-CeO₂ photocatalysts at a concentration of 25% achieved the highest degradation efficiency, with nearly 41.5% removal of Remazol Turquoise Blue and 26.1% removal of Remazol Brilliant Red after 120 min. Increasing the photocatalyst concentration increases the number of active sites, accelerating the degradation process. However, there is a limitation at very high concentrations because of the potential for catalyst particle agglomeration.

Abstract

Community-Based Total Sanitation (STBM) is a strategy to sanitation development that was established in response to the high prevalence of diarrhea caused by poor sanitation in Morokrembangan Village, which resulted from the community's behavior of defecating anywhere. This approach facilitates the community empowerment process to analyze the situation and risks of environmental pollution caused by open defecation. This research aims to determine the effect of the first pillar of the Community Based Total Sanitation (STBM) program, namely Stop Open Defecation (STOPS) in Morokrembangan Village. Using the method proposed by finsterbusch and motz, namely the Single Program Before-After assessment/evaluation. The existence of the STBM program has had a positive influence on society. The positive influence here can be seen from various aspects, such as positive influence in the form of changes in the environment, health, socio-culture, physical condition of latrines.

Abstract

Contamination of river water by suspended particles and organic matter increases total suspended solids (TSS) and turbidity, degrading water quality and posing risks to aquatic ecosystems and public health. This study evaluated the performance of chitosan derived from green mussel shells (Perna viridis) compared to polyaluminium chloride (PAC), a conventional coagulant, in reducing TSS and turbidity. Chitosan was selected due to its cationic polymer properties, which are obtained through the conversion of chitin, enhancing its coagulation–flocculation effectiveness. The experiment employed a jar test with variations in pH (5, 7, and 9), coagulant dosage, and standardized mixing protocols. Results showed that chitosan achieved optimal performance at pH 5 with a 150 mg/L dosage, resulting in 82% TSS removal and 87% turbidity reduction. In contrast, PAC performed best at pH 7 with a 20 mg/L dosage, achieving 85% TSS removal and 87% turbidity reduction. Particle Size Analyzer (PSA) results indicated that PAC produced larger and more uniform flocs (Xav = 1796.71 nm; PI = 0.403) compared to chitosan (Xav = 1070.28 nm; PI = 0.444). Although PAC had slightly higher efficiency, chitosan from mussel shell waste shows strong potential as an environmentally friendly coagulant for treating river water.

Abstract

The electroplating industry generates wastewater containing hazardous heavy metals such as copper (Cu) and nickel (Ni), which can contaminate aquatic and terrestrial environments. Initial tests showed Cu and Ni concentrations of 92.6 mg/L and 76.23 mg/L, respectively—far exceeding the permissible limits. To address this issue, an environmentally friendly treatment technology was employed, using a subsurface-flow constructed wetland planted with Cyperus papyrus. The study used combinations of soil and rice husk biochar media at weight ratios of 1:0, 1:1, 1:2, and 2:1. Aeration pretreatment was conducted for 24 hours before wastewater was introduced into the subsurface flow wetland. The hydraulic retention times were 0, 5, 10, and 15 days. The results indicated that the 2:1 media combination under aerated conditions achieved the highest removal efficiencies—93.02% for Cu and 96.81% for Ni on the 15th day. Plant tissue analysis revealed the highest metal accumulation in the roots, with Cu and Ni contents of 0.315 mg/g and 0.241 mg/g, respectively.

Abstract

As ship repair and maintenance activities increase in the floating dock area of PT PAL Indonesia, they consequently affect the surrounding seawater quality. However, at present, the determination of seawater pollution levels is still conducted through manual sampling followed by laboratory analysis, which requires a considerable amount of time. Therefore, an IoT-based seawater quality monitoring system is proposed as a solution to this problem. The objectives of this study were to determine the level of seawater pollution in the floating dock area and to analyze the relationship between independent variables and the dependent variable. This study employed a quantitative research method consisting of three stages: first, the design and assembly of the monitoring device; second, sampling at each predetermined location; and third, correlation testing to determine the relationship between independent variables and the dependent variable using the Pearson correlation method. The results showed that the average values of pH, temperature, turbidity, salinity, and dissolved oxygen were 7.04, 27.60 °C, 4.88 NTU, 32.25 ‰, and 8.25 ppm, respectively. The study concludes that the seawater quality in the floating dock area still meets the seawater quality standards in accordance with the Decree of the Minister of Environment of the Republic of Indonesia Number 51 of 2004, and that there are two independent variables that are significantly correlated with the dependent variable.

Abstract

Liquid waste from metal-plating industries is known to contain copper (Cu²⁺), which is toxic to living organisms if not properly treated. Hydrilla verticillata is an invasive aquatic plant capable of rapid growth and heavy metal accumulation, making it a potential candidate for use in wastewater treatment through phytoremediation. This study aims to analyze the effect of the weight of Hydrilla verticillata on the reduction of Cu²⁺ concentration in metal-plating wastewater. The wastewater used in this study was effluent that had undergone preliminary treatment with the addition of lime and NaHCO₃. The experiments were carried out in a 5-liter laboratory reactor for 15 days, including a 5-day acclimatization period and a 7-day initial toxicity test (Range Finding Test). The weight variations of Hydrilla verticillata used were 75 g, 100 g, and 125 g. The results showed that Hydrilla verticillata was able to reduce Cu2+ concentration by up to 99.05% at a weight of 125 g within 15 days. This indicates that the weight of Hydrilla verticillata significantly influences the reduction of copper (Cu2+) in metal-plating industrial wastewater.

Abstract

The utilization of coffee waste as an alternative fuel is a potential strategy in supporting organic waste management and the transition towards renewable energy. This research aims to analyze the effect of variations in the composition of coffee grounds and husk, as well as the type of binder, on the characteristics of bio-briquettes, while also evaluating the greenhouse gas (GHG) emissions generated during their production process using a Life Cycle Assessment (LCA) approach. The experimental method was carried out through the carbonization process of coffee waste at a temperature of 450°C for 80 minutes, followed by mixing the 60-mesh charcoal with bentonite and pulp binders. Characteristic testing, including moisture content, ash content, calorific value, and combustion rate, referred to SNI 01-6235-2000, while the LCA analysis was conducted using SimaPro software with the IPCC GWP100 (2021) method. The results showed that the combination of 100% coffee grounds with a pulp binder produced the best performance with the lowest moisture (4.2%) and ash (1.2%) content, a high calorific value (>6,000 cal/g), and a stable combustion rate. Thus, this combination is recommended as it yields optimal quality while lowering the environmental impact of production. The carbonization stage was the largest contributor to GHG emissions (25.11 kg CO₂-eq/kg product), followed by oven drying (3.77 kg CO₂-eq/kg). These findings affirm the importance of raw material optimization and energy efficiency in enhancing the quality and sustainability of bio-briquette production.

Abstract

The increasing volume of organic waste, especially market vegetable waste and animal waste, poses a challenge in environmental management because it has not been optimally utilized as a renewable energy source. This study aims to analyze the effect of the mixture ratio of horse manure and organic waste on biogas production using the anaerobic co-digestion method. The main ingredients consist of horse manure and market vegetable waste with the addition of Effective Microorganism 4 (EM4) starter and biogas probiotics. Variations in the mixture ratio used include 20:80, 30:70, and 50:50 (horse manure: vegetable waste). The parameters observed include methane (CH₄), carbon dioxide (CO₂), and C/N ratio. The results showed that the 50:50 ratio with the addition of EM4 produced the best performance with a methane content of 58.35% and CO₂ of 41.65%. These findings indicate that a balanced mixture composition and the use of EM4 can increase microorganism activity and accelerate the fermentation process. Thus, selecting the right substrate ratio and appropriate inoculum can be a potential strategy in developing environmentally friendly biogas energy.
